NOTICE
The mapping information is stored in C:\system\Log\TableMapping_timestamp*.log file (approx.
459KB).
The Delta of Gantry to fiducials` positions should be ≤ 20µm (0.020mm).
4.4.2 Table Mapping: Verify
For verification of positional accuracy of the camera across the work area.
Verify saves time. It takes only 5.5 minutes compared to 63 minutes in Teach.
The procedure is similar to the Teach procedure.
Verify the table mapping again if:
●
The machine is already calibrated but is moved.
●
The positional accuracy of the camera across the work area is suspect.
●
Maintenance is performed on the gantry axes e.g. greasing.

machine cover.
► Install the Coaxial Light Assembly and
position the Mapping Plate on the con-
veyor.
► Click Ok.
Step 4

Step 5
Fig.238: “Focus” icon
► Click on Focus icon (1).
► Adjust Focus (2) between 50 ~ 60.
► Click Continue (3) to start the teach table
mapping process.
The progress of the mapping is continu-
ously reported.
NOTICE
At 50% completion, the table towers, the stopper rises, and the plate will move forward to the stopper
to continue the second stage of the mapping. Do not be alarmed by this sudden movement. No user
intervention is required.
Step 6
Fig.239: Message”
► A message pops up asking for the removal
of the coaxial light and mapping plate.
Click Ok (1) once completed.
Fig.240: Message
► A successful verification is completed.
Click Ok (1).
NOTICE
If the mapping fails, clean the plate and repeat the procedure. Mapping failures are caused by a fail-
ure to read a fiducial on the plate – usually caused by fingerprint smudges on the fiducials. Verifica-
tion of the mapping results is necessary after a successful Teach.
